LangJournal helps you learn a language by keeping a diary, with AI corrections, explanations, follow-up questions, and review exercises. Write about your day in the language you're learning. AI checks grammar and unnatural expressions and helps you make your writing clearer and more natural. Each correction comes with an explanation, so you can understand why a change is needed and develop your writing skills. When you're unsure about an expression, you can ask AI directly. Ask questions about your diary, such as "Does this sound natural?", "What's the difference between 'the' and 'a'?", or "How can I say this more casually?" Keeping a diary is a way to practice writing and build a daily habit of using the language. Start with one short sentence and gradually build your grammar, vocabulary, and range of expressions. [Key Features] ■ Write a Diary With AI Corrections AI checks your diary as soon as you submit it. Get help with grammar, vocabulary, and unnatural expressions to make your writing more natural. ■ Understand Why a Correction Is Needed See why each corrected part needs to change. Review your writing with explanations, rather than just looking at the corrected answer. ■ Ask AI About Your Diary Ask AI any questions you still have after a correction. Explore nuances, grammar, alternative wording, and more natural ways to express yourself. ■ Review Your Mistakes Review by writing sentences in exercises based on corrections from your diary. Practice reducing repeated mistakes and reinforcing what you've learned. ■ Look Back With Weekly Reports Review your diary entries, AI chats, words used, and words used for the first time each week. See how many days you've practiced and how much you've done to help build a learning habit. ■ Check Your English Level With CEFR Analysis Analyze your diary against CEFR levels to get an indication of your English proficiency. See an overall assessment and breakdowns covering vocabulary, grammar, and verb forms. This feature is currently available for English learners. ■ Learn by Chatting With AI Characters Talk with AI characters such as Zena, Zeb, Leon, and Mari by text or voice. Build on topics from your diary or discuss a topic you enjoy to get more practice using the language. ■ Learn in 13 Languages Study English, Korean, Japanese, Chinese, Spanish, German, French, Italian, Portuguese, Dutch, Polish, Swedish, or Tagalog. ■ Share Diaries With a Team Join a team to share diary entries and exchange comments with others learning the same language. Learning together can help you keep going when it's hard to stay consistent on your own. This feature is currently available for learners of English, German, and Korean. ■ Get Daily Support From Zena Zena supports you with comments based on your learning activity. Start with a short diary entry and find encouragement to keep learning each day. [Recommended For] ■ Learners who want to develop natural expressions by keeping a diary ■ People who want to practice writing with AI corrections ■ Learners who want to understand their mistakes and avoid repeating them ■ People who want to learn at their own pace while asking AI questions ■ Learners who want more opportunities to use the language every day ■ People who find it hard to stay consistent alone and want to enjoy learning languages

Keep a diary in English and get it reviewed as you write it. Finish a sentence and endiary reads that sentence right away. Not when you submit, not when you ask — the moment you put a full stop on it. The wording it would change is underlined in your own text, and the correction sits below with one short line telling you why. Tap once and the fix goes back into your writing. No copying, no retyping, no switching to another app to check something. When you are done, endiary reads the whole entry once more. That last pass looks at what a sentence-by-sentence check cannot see: whether your tenses hold together, which habit is costing you the most, and the words you were reaching for but did not have yet. You get your entry rewritten the way a native speaker would have written it — still in your voice, still at your level. WHAT YOU GET • Review as you write, one sentence at a time • The exact words to change, underlined where you wrote them • One short reason for each correction, in plain language • One tap to apply a fix • A final review of the whole entry: what worked, what to practise next, and your entry polished • Vocabulary drawn from what you actually wrote about, not a word list • Every entry kept, so you can read back what you wrote and what you learned that day WHY WRITE INSTEAD OF DRILL Grammar exercises test what you already know. Writing about your own day makes you reach for what you do not know yet — and that gap is exactly where the correction lands. A diary gives you something to say every single day, which is the hard part of practising a language on your own. SIGNING IN Sign in with Apple or Google to keep your entries. You can also start without an account and connect one later; guest entries are removed after 30 days of inactivity. Your entries are yours. They are used to write the review you asked for and nothing else. ENDIARY PRO Everything above is free. Pro is an optional auto-renewable subscription — Weekly, Monthly or Yearly — that gives you a higher daily review quota, keeps your entries in sync across your devices, and removes ads. Payment is charged to your Apple ID account when you confirm the purchase. The subscription renews automatically unless you cancel it at least 24 hours before the end of the current period. You can manage or cancel it in your App Store account settings.

Verdict
The clearest difference is ads: Language Diary at none against endiary's shown. Language Diary also leads on update cadence (every 3 days vs fortnightly). On price, in-app purchases, device support and iOS requirement there is nothing between them.
